This Small Business Technology Transfer(STTR)- Phase II project will develop and test an interactive web-enabled television program, titled Mothers Exercising or ("MomZing). Features include the ability to select one to five 10-minute videos demonstrating yoga, aerobics, and strengthening exercises for mothers with infants 2 to 8 months of age. Women will select and sequence together videos personalized to their fitness level, preference for exercise type, and the choice to actively exercise with her baby or alone. Exercises with a baby will be tailored to the infant's weight and include interactions that promote cognitive development and mother-child bonding. MomZing is designed for viewing on a television taking advantage of new technologies that allow viewers to watch streaming video (including movies) from the internet on a television. The television can also be connected to the internet via a web-enabled console such as an internet-connecting device.
